Part I. Why Korean Manufacturing Cannot Escape Automation
1) Demographic Pressures — “Robots as a Necessity, Not a Choice”
Korea’s demographic changes are more than a social issue; they threaten the very foundation of its manufacturing sector.
Rapid Aging: According to Statistics Korea, seniors (65+) accounted for 22% of the population in 2025, well above the OECD average of 18%. By 2035, the figure will approach 30%, surpassing even Japan’s aging trajectory.
Shrinking Workforce: The working-age population (15–64) is already in decline. By 2040, it is projected to shrink by over 5 million people, equivalent to the entire population of Seoul disappearing from the labor market.
These changes hit labor-intensive industries the hardest. Small and medium-sized enterprises (SMEs) in core manufacturing sectors such as casting, molding, welding, and plating struggle to hire workers, with some reporting idle production lines simply due to labor shortages.
Reliance on foreign labor has been rising, but this too has limits given minimum wage hikes, stricter labor regulations, and training issues. The reality is clear: robots are becoming the only viable solution to sustain production.

2) Rising Minimum Wages and Cost Pressures
Wage structures are another driver pushing firms toward automation.
Minimum Wage Growth: Korea’s minimum wage rose from KRW 5,580 in 2015 to KRW 9,860 in 2025 — a 77% increase in just a decade, far outpacing inflation (~20%).
Corporate Burden: With wage growth exceeding productivity gains, firms are forced to seek efficiency through automation and robotics.
Case studies illustrate the economics:
An auto parts maker replaced 20 assembly line workers with five collaborative robots (cobots), investing about KRW 700 million. The company recouped its costs in just two years, while reducing overtime and maintaining output.
An electronics supplier introduced AI vision robots in camera module assembly, cutting defect rates from 3% to 0.5%. This improved not only costs but also quality competitiveness.
The cycle of investment → savings → reinvestment has made robots a rational choice not only for conglomerates but also for SMEs seeking long-term survival.

3) The Expansion of Smart Factories
Major Korean conglomerates are moving beyond the concept of smart factories toward near-total automation:
Samsung Electronics: Thousands of industrial robots and AGVs (Automated Guided Vehicles) already handle semiconductor wafer processes, with AI systems analyzing data to minimize defects.
Hyundai Motor: Over 70% of welding, painting, and assembly at the Ulsan plant is automated. Logistics automation is also being deployed, edging closer to “lights-out” factories.
LG Electronics: Collaborative robots are now handling physically demanding tasks on appliance assembly lines, improving both productivity and worker safety.
This transformation cascades down the supply chain. Tier-1 and Tier-2 suppliers must match these productivity standards, prompting widespread adoption of automation. This creates opportunities for robot parts makers (precision reducers, sensors), control software developers, and logistics automation providers.
According to the International Federation of Robotics (IFR), Korea’s robot density in manufacturing reached 1,012 units per 10,000 workers in 2023, the highest in the world — more than double Germany (397) and Japan (399). Korea is already a frontrunner in automation, and structural pressures suggest the gap will only widen.
---
📌 Summary
Korean manufacturing faces a “triple squeeze” of aging demographics, rising labor costs, and global competition.
Labor shortages → Robots are unavoidable
Rising wages → Automation is cost-effective
Conglomerate standards → Suppliers must follow
In short, robots are not a choice but a survival strategy, and at the same time, a compelling investment theme.

Part II. Robotics Meets AI — From Software to Hardware
1) Beyond ChatGPT: How AI Enters the Factory Floor
The launch of ChatGPT in 2023 made AI a household term and a disruptive force across industries. While AI has long been associated with data analysis and language processing, its true impact comes when paired with physical execution through robotics.
Traditional industrial robots excelled at simple, repetitive tasks like welding and painting but lacked adaptability. Today, with AI integration, robots are moving into far more sophisticated roles:
Computer Vision: Detecting defects in real time with high precision
Machine Learning Algorithms: Handling delicate assembly and irregular logistics sorting
Autonomous Navigation: AGVs optimizing warehouse transport paths without human guidance
In short, if ChatGPT disrupted knowledge work, AI-driven robots are now transforming manual manufacturing work.
